Coexpression of body pattern components in living oval squid. Various body patterns of oval squids were observed in the wild and in the laboratory. These body patterns are composed of different numbers of components. A, Six body pattern components are shown, but some of them were only weakly expressed. B, Four distinct components are expressed in this oval squid. C, Three components are shown in this male oval squid when attempting to mate with a female. D, Four components are expressed differentially in this squid. The numbers on the top indicate the expression level of individual components.
